I too have returned to playing some competitions after a 25 year lay off, and everytime a "youngster" tees it up with me I flashback to when I was kid and I scared the heck out of the adults with my long drives and total lack of fear. Now I know how it must have felt to have a 15 year old hand you your lunch.
I've been playing a lot of golf lately with a new guy on our maintinence crew who plays to a 1 handicap. He considers the Portsmouth (NH) Country Club his "home course" and still maintains his membership there. He pushes me to focus, take my time to look at my shot, and use better course management, two things I thing you lose when you stop competing. The results have been some of the best golf I've played in years.
